A solid cylinder of mass M and radius R is resting on a horizontal platform (which is parallel to the x-y plane) with its axis fixed along Y-axis and free to rotate about its axis. The platform is given a motion in the X-direction given by x=Acos(ωt). There is no slipping between the cylinder and the platform. The maximum torque acting on the cylinder during its motion is:
